a) HN is more than 1 person. People will have various opinions
b) NPM is a repo for open source. Garbage can be easily inspected. I have no issues with packages I am using. Decompiling APKs is not something I am keen to do
c) 20 testers won’t raise Play store quality. Scammers already have click farms or can purchase this for cheap. Better automated review tools and more importantly more humans in loop can help the quality. Maybe submitting code to 3rd party to get some “seal of approval” (not mandatory but boosting score?)
This 20 tester requirement also does very little to actually improve quality or stop 'garbage' from being listed.
